Abstract (en)

[origin: EP2642537A2] According to one embodiment, a light emitting device includes a light emitting element, a translucent section, and a light distribution control section. The light emitting element includes a first surface. The first surface emits light. The translucent section is provided on the first surface. The light distribution control section is provided on a periphery of the first surface. The light distribution control section has a lower refractive index than the translucent section.
